Part B - Searching and Sorting 1. Create a search method in your program that allows the user to find a tax payer and display their information to the user. Change your program to prompt the user for a name to find. Have the main method call this method. 2. Add code to your program to sort the information according to salary in ascending order. Save the sorted information into a new file.

Transcribed Image Text:Part B - Searching and Sorting
1. Create a search method in your program that allows
the user to find a tax payer and display their
information to the user. Change your program to
prompt the user for a name to find. Have the main
method call this method.
2. Add code to your program to sort the information
according to salary in ascending order. Save the sorted
information into a new file.
Part C-Suggested enhancements (for an even more
satisfied customer)
1. Ask the user for all file names instead of hard coding
them in the code.
2. Change your text based application into a graphical
user interface application.
3. Create code to sort the file according to the tax payer
names in alphabetical order.
4. Move the sort code from the main method into
methods. Note that the sort method needs to have as
input all of the arrays.
5. Use a JTextArea or other more interesting means to
display your results on the screen.
6. Add information to your input file that will allow you
to create arrays of sizes defined within the input file.
This way Revenue Canada could use files of different
sizes with your application.
7. Include Error Trapping structures to deal with
possible errors.
